Enum mz_repr::global_id::GlobalId

pub enum GlobalId {
    System(u64),
    User(u64),
    Transient(u64),
    Explain,
}

The identifier for an item/object.

WARNING: GlobalId’s Ord implementation has at various times expressed:

• Dependency ordering (items with greater GlobalIds can depend on those lesser but never the other way around)
• Nothing at all regarding dependencies

Currently, GlobalIds express a dependency ordering. We hope to keep it that way.

Before breaking this invariant, you should strongly consider alternative designs, i.e. it is an intense “smell” if you need to allow inverted GlobalId dependencies. Most likely, at some point in the future, you will need to invert the dependency structure again and will regret having broken it in the first place.

Variants

System(u64)

System namespace.

User(u64)

User namespace.

Transient(u64)

Transient namespace.

Explain

Dummy id for query being explained

Implementations

impl GlobalId

pub fn is_system(&self) -> bool

Trait Implementations

impl Arbitrary for GlobalId

type Parameters = (<u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Union<BoxedStrategy<GlobalId>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for GlobalId

fn clone(&self) -> GlobalId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Columnation for GlobalId

type InnerRegion = CopyRegion<GlobalId>

The type of region capable of absorbing allocations owned by the Self type. Note: not allocations of Self, but of the things that it owns.

impl Debug for GlobalId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GlobalId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GlobalId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for GlobalId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for GlobalId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MzReflect for GlobalId

fn add_to_reflected_type_info(rti: &mut ReflectedTypeInfo)

Adds names and types of the fields of the struct or enum to rti.

impl Ord for GlobalId

fn cmp(&self, other: &GlobalId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for GlobalId

fn eq(&self, other: &GlobalId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GlobalId

fn partial_cmp(&self, other: &GlobalId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RustType<ProtoGlobalId> for GlobalId

fn into_proto(&self) -> ProtoGlobalId

Convert a Self into a Proto value.

fn from_proto(proto: ProtoGlobalId) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for GlobalId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
